simple-assert Build Status

Vanilla Assertions

A simple assert wrapper around chaijs/assertion-error. This probably won't be useful to the average user unless you are a minimalist; you probably want Chai. We use it to avoid circular dependencies when testing Chai's dependencies.

Installation

Node.js

simple-assert is available on npm.

$ npm install simple-assert

Component

simple-assert is available as a component.

$ component install chaijs/simple-assert

assert(1, '1 is truthy');

assert.not (expr[, msg])

  • @param {Mixed} express to test for falsiness
  • @param {String} messag eon failure

Perform a falsey assertion.

db.get(123, function (err, doc) {
